IMPROVEMENT IN MAKING SHEET-METAL SPOUTS.

Spccilicaticn forming part of Letters Patent No. 165,596, dated July 13, 1875; application filed May 8, 1875.

To all whom it may concern:

Be it known that 1, MILETUs S. LEIDY, of Richmond, in the county of Henrico and State of Virginia, have invented a new and valuable Improvement in Machines for Manufacturing Spouts; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being bad to the annexed drawings, making a part of this specification, and

to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a side elevation of my machine, and Fig. 2 is a plan view of the same. Fig. 3 is a side view, part sectional, and Figs. 4, 5, 6, 7, and 8 are detail views. I

This invention has relation to improvements in devices which are specially designed for forming the spouts of kettles and other like vessels of sheet metal; and the nature of the invention consists in combining, with a tapering mandrel and a detachable inclined die-bed arranged thereon, a sectional former, adapted to be actuated to embrace the said mandrel, whereby a spout will be formed out of a sheetmetal blank, as will be hereinafter more fully explained.

In the annexed drawings, A designates a platform or table, supported by suitable legs a, upon which my improved spoutforming device is designed to be mounted. This mechanism consists of a conical mandrel, B, which is supported in a horizontal position at both ends, and of a former, composed of sections 0 G, the one above and the other below the said mandrel, which sections are hinged to vibrate to and from the said mandrel, and are of such a shape that they will snugly embrace and inclose the same when they are caused to vibrate inward upon it, as shown in Fig. 3. The upper section 0 of the former is rigidly but detachably secured to a vertically-vibrating lever, D, fulcrumed at d to an upright, E, arranged within a tubular cylinder, F, which upright is maintained in position by means of a nut, b, applied upon its lower end, projectin g through tableA. Cylinder F rotates freely on rod E, and sustains one end of mandrel B, by means of a lug, c, on its end, which is received into a perforation in the said cylinder,

S will be strongly compressed, so that the moment the mandrel is released the reaction of the said spring will cause it to be returned to its proper position under section 0 of the former, when it will be received upon a rest, G, at its other end. This rest has a stop, 0, under which a projection, f, on the end of the mandrel will be received, thus preventing it from undue displacement, when it is returned to its proper position by spring S. The shock occurring when the mandrel is arrested by stop 6 is softened by means of a spring, 8, on the said stop, and the casual disarrangement of the mandrel, with relation to the dies or formers (l O, is thus effectually prevented. Lever D is actuated for the purpose of cansing die-O to embrace the mandrel by means of a vertically-reciprocating rod, H, passing through platform A, and operated by a suitable treadle, which rod is provided as to its upper end with a slot, through which the said lever passes, as shown in Fig. 1. The lower die or former O is pivoted at f to an upright, I, near cylinder F, which is rigidly secured to the platform and is actuated to embrace the lower surface of mandrel B, by means of a vertically-vibrating U -shaped lever, J, having its fulcrum on the said platform A.

When lever J is actuated by means of a handle, g, its weight-arm, which is provided with a grooved anti-friction pulley, g, will raise the said former forcibly against the mandrel. By this means a sheet-metal blank, K, when it is interposed between the mandrel and the upper die or former G, will be bent by the latter over the mandrel when it is forcibly brought into contact therewith, thus form in g a little more than one-half the bend of the spout, the remaining bend being supplied by means of the lower former O, which will bring the tapering edges h of the blank togetherifor soldering. The upper end of this blank, when the flanges for fastening the spout to the vessel are designed to be made thereon, will be provided with an arrowheaded extension, h, and it will be swaged to form a neb, z, and flanges 'i on the spout 0,

(shown in Fig. 8,) by means of a detachable die-bed, L, which is passed on mandrel B with its upper-inclined flanged front .eclge.

upward. These flanges, designated by the letter j in the drawings, extend outward from the die, and upward beyond the sa1ne,-.a .re-

cess, j, being cut slightly in rear of thepoint of the said bed in which the point of the arrow-headed blank h is designed to be received. The inner end of the upper former 0 is beveled, sothatwhen it is actuated for the formation ofa spout itshall fit snugly over. the front "inclined end of the die bed, as

shown in Fig. 3.

When the blank K (shown in Fig. 7) is.

placed upon themandrel with its point in-re cess j of =the.diebed the beveled front end of the upper former .will ,form the-n6 and the flanges z" of thespout at thesame-time bend.-.

ing the body Qffthe blanlnover the mandrel,

shapingout rather more thammJe-half ot the spout thelower former being then'forcibly thrown up will shape out the .remainderof the spout, and bring'theedges h. of the blank .close together so that they maybe .eonveniently soldered together.- The footis then removed from the treadle actuating the upper.- former to springback under the i1npulse;i m-- rotating on mandrel B, it is provided with an inwardly-projecting flange, a, in the nature of a spline, which is received into a correspondingly-shaped recess, '1, in the said mandrel, thus holding the die in a constant position.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a machine for making sheet-metal spouts, theconcave formers O 0, adapted to be successively operated in combination with a tapering mandrel, B, substantially as specified. r

2. The die-bed L, having flanges j and recess j, in combination with a mandrel, B, and the formers O 0, adapted to be actuated t0 inclose the same, substantiallyas specified.

3. The combination of a rest, 0, and a spr ng, 8,. applied thereon, witha horizontallyvibrating mandrel, B, adapted to beautomatically returned by spring S to its rest Gr, substantially as specified.

4. The tapering mandrel B, having longitudinal groove 4', in combination with a detachableflanged die-bed, L, having flange n,

substantially-as specified.

,5. The. mandrel B, in combination with cylinder F, rotating on rod E, substantially as specifie 6. The u-shaped leverJ, having grooved antifriction roller g, in combination with a gravitaingformer U and a'fixed .mandrel 13, substantially as specified,

7. The sheet-metal blank K, having tapering edges .hand an arrow-headed extension, h adapted to be formed into a spout, 0, havin g a neb,,c', and flanges '5, whereby it is riveted to a vessel,substantially as specified.
